Going to a Britain school for one year was a very enjoyable and exciting experience for me. I was very happy with the school hours in Britain  31  school starts around 9 a.m. and ends about 3.30 p.m. This means I could get up an hour  32  than usual as schools in China begin before 8 a.m.

On the first day, all students went to  33  assembly. I sat next to a girl whose name was Diane. We  34  became best friends. During  35 , the headmaster told us about the rules of the school. He also told us that the best way to  36  respect from the school was to work hard and  37  high grades. This sounded like my school in China.

My English improved a lot as I used English every day. I usually went to the Computer Club at lunch time, so I  38  e-mail my family and friends back home  39  free. I also had an extra French class on Tuesday evenings.  40  was really fun as I learned how to buy, prepare and cook food.
